Please help ive asked this so many times.

Find the area of each shape. Use 3.14 for π

divide by 3.14 on both sides first.

V/3.14 = r^3

Now cube root both sides.

3√(V/3.14) = r

r = 3√(V/3.14)

r is the cube root of v/3.14.

Step-by-step explanation:

The remainder on dividing f(x) by (x + h) is f(- h)

Given

f(x) = - x³ - x² + 3 , then

f(- 3) = - (- 3)³ - (- 3)² + 3 = - (- 27) - (9) + 3 = 27 - 9 + 3 = 21 ← remainder

Answer:

r = 55.2 cm

Step-by-step explanation:

the arc length is calculated as

arc = circumference × fraction of circle

     = 2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] ( r is the radius )

given arc = 63.48π , then

2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] = 63.48π ( cancel 2π on numerator/ denominator )

r × [tex]\frac{23}{20}[/tex] π = 63.48π ( divide both sides by π )

[tex]\frac{23r}{20}[/tex] = 63.48 ( multiply both sides by 20 to clear the fraction )

23r = 1269.6 ( divide both sides by 23 )

r = 55.2 cm

The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

John is playing a game of darts. In this game of dart,

The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.

Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,

[tex]P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}[/tex]

Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

A(diff)/A1×100=96.01%

[tex]r_{2}[/tex]Answer:

D) 96%

Step-by-step explanation:

let the circumference of circle be C = 2π[tex]r_{1}[/tex] and   [tex]r_{1}[/tex] =   [tex]d_{1}[/tex]/2

Initial radius (radius before increment) = [tex]r_{1}[/tex]

initial diameter (diameter before increment) = [tex]d_{1}[/tex]

Increasing the circumference of a circle other factors are constant except the radius which can be used to find the diameter hence increasing the circumference of a circle is equivalent to increasing the diameter

area of the circle before increment [tex]A_{1}[/tex] = π[tex]r_{1}[/tex]²

[tex]A_{1}[/tex] = π × ([tex]d_{1}[/tex]/2)²

[tex]A_{1}[/tex] = π[tex]d_{1}[/tex]²/4

Increment of circumference results to increment of only the diameter

diameter after increment by 40%, [tex]d_{2}[/tex] = 1.4[tex]d_{1}[/tex]

1.4 represents increment by 40%

radius after increment [tex]r_{2}[/tex]  =  [tex]d_{2}[/tex]/2 = 1.4[tex]d_{1}[/tex]/2 = 0.7[tex]d_{1}[/tex]

area after increment, [tex]A_{2}[/tex] = π[tex]r^{2} _{2}[/tex]

[tex]A_{2}[/tex] = π(0.7[tex]d_{1}[/tex])²

[tex]A_{2}[/tex] = π × 0.49[tex]d_{1}[/tex]²

Change in area =  [tex]A_{2}[/tex] - [tex]A_{1}[/tex]  

[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π ×  0.49[tex]d_{1}[/tex]² - π [tex]d_{1}[/tex]²/4

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]  = π [tex]d_{1}[/tex]²(0.49 - ¼)

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]  = π [tex]d_{1}[/tex]²(0.49 - 0.25)

[tex]A_{2}[/tex] - [tex]A_{1}[/tex]   = 0.24 π[tex]d_{1}[/tex]²

Percentage increment = ([tex]A_{2}[/tex] - [tex]A_{1}[/tex]/ [tex]A_{1}[/tex]) × 100

= ((0.24 π[tex]d_{1}[/tex]²)/(π[tex]d_{1}[/tex]²/4)) × 100

= (0.24 × 4 ) × 100

= 0.96 × 100

= 96 %

Answer:

There is very very very near 1,000,000 (shades included in those colors)

Step-by-step explanation:

Hi!there are about 18 decillion colors.So how do we know there are 18 decillion colors? First of all, scientists have determined that in the lab we can see about 1,000 levels of dark-light and about 100 levels each of red-green and yellow-blue. So that's about 10 million colors right there. And then you have to allow for other matters.

Answer:

84 cm

Step-by-step explanation:

Equilateral triangle have sides that measure the same

so

3x-2 = 18+x

Subtract x from each side

3x-2-x =18+x-x

2x-2 = 18

Add 2 to each side

2x-2+2 = 18+2

2x= 20

Divide by 2

2x/2 = 20/2

x = 10

The side measures18+x = 18+10 = 28

The perimeter is 3 times the length of one side

3*28 = 84
